My RGH is Black Screening.

u launched any other mod memu before that

 

try reboting ur rgh then try other mod menus can cause that

 

Iron Wolf v2 will shut down your RGH off if you attempt to run the default_mp.xex, if you haven't acquired legitly.

To fix this:

1) Disconnect your ethernet / wireless connection.
2) Sign out of your profile(s)
3) Launch default_mp.xex, then it will ask you what you want; Public Cheater / Host
4) Re-connect your ethernet once your signed back into your profile.
